Wi-Fi (wlan0) not working on H96Max M1

[3735943886]

Description

Since the H96Max M1 is not officially supported, I am using the H96Max M2 image instead. While the H96Max M2 support works for the majority of the hardware features on the H96Max M1, there is a specific regression regarding networking. Most core peripherals are functioning correctly, but the Wi-Fi interface (wlan0) is unavailable.

Observed Behavior

• Working: HDMI, USB, and system stability.
• Not Working: Wi-Fi (Interface exists but cannot be activated due to firmware loading errors).

Diagnostic Logs (dmesg)

The kernel identifies the SDIO card as BCM4334/3, but it fails to load the required firmware files:

pi@armbian:~$ dmesg | grep -i "sdio"
[    8.153111] mmc2: new ultra high speed SDR50 SDIO card at address 0001
[   13.935187] brcmfmac: brcmf_fw_alloc_request: using brcm/brcmfmac4334-sdio for chip BCM4334/3
[   13.949493] brcmfmac mmc2:0001:1: Direct firmware load for brcm/brcmfmac4334-sdio.mangopi,m28k.bin failed with error -2
[   13.956611] brcmfmac mmc2:0001:1: Direct firmware load for brcm/brcmfmac4334-sdio.clm_blob failed with error -2

Analysis

It appears the H96Max M1 uses the Broadcom BCM4334 chipset via SDIO, but the current H96Max M2-based configuration is looking for a specific firmware naming convention (.mangopi,m28k.bin) which is missing in the /lib/firmware/brcm/ directory.

Questions / Request

Any suggestions on how to get the wlan0 working on the H96Max M1?

cd /usr/lib/firmware/brcm
sudo ln -s brcmfmac4334-sdio.bin brcmfmac4334-sdio.mangopi,m28k.bin
sudo ln -s brcmfmac4334-sdio.txt brcmfmac4334-sdio.mangopi,m28k.txt
sudo rmmod brcmfmac
sudo modprobe brcmfmac

cd /usr/lib/firmware/brcm
sudo ln -s brcmfmac4334-sdio.bin brcmfmac4334-sdio.mangopi,m28k.bin
sudo ln -s brcmfmac4334-sdio.txt brcmfmac4334-sdio.mangopi,m28k.txt
sudo rmmod brcmfmac
sudo modprobe brcmfmac

Thank you for the prompt response.

Following your suggestions, one of dmesg errors has disappeared. The .clm_blob error persists, but I assumed it might not be critical for the time being.

Unfortunately, I am still unable to connect to Wi-Fi. Here are some specific observations regarding the behavior:

1. Scanning works: I can see the list of available APs without any issues.
2. Connection attempts: I can initiate a connection to an AP.
3. Error -16: The connection consistently fails with error 16 (confirmed via journalctl), even after reconfiguring the AP to have no password.
4. Tools used: I have tried using both armbian-config and nmtui across several resets, reboots, and different APs.
5. DTB testing (M1): I tried the H96Max M1 DTB from [this repo](https://github.com/ilyakurdyukov/rk3528-tvbox), but the result was the same.
6. DTB testing (M7): I also tried the H96Max M7 DTB mentioned in [this issue comment](First boot on H96 Max M1 ilyakurdyukov/rk3528-tvbox#7), but the TV box failed to boot, and I had to re-flash the image.

Any further hints or suggestions on how to resolve this? Thank you!
